[0018] The frame 10 is formed by aluminum-extrusion and has a top plate 11, two side plates 12, and two bottom plates 13 formed by the side plates 12 being bent inward at the bottom fringes of the side plates 12. A recessed portion 14 having two free ends at two sides thereof is encompassed by inner sides of the top plate, the side plates, and the bottom plates to be formed along a longitudinal axle of the frame. Additionally, two elongated slots 111 are axially located at the top plate 11 and communicate with the recessed portion 14. Two T-shaped rails 121 are respectively inwardly recessed along the longitudinal axle of the frame at two exterior sides of the side plates 12. A plurality of locating holes 122, as shown in FIG. 4, are axially located at the bottom of one of the rails 121. Additionally, each of the bottom plates 13 is provided with a plurality of pads 15 at the external portion thereof for supporting the body exercising trainer 100 on the ground.

[0019] Each support 20 includes a transverse bar 21 and a connecting bar 22, which can be inserted into one of the two free ends of the recessed portion 14. The side plates 12 and the connecting bar 22 are inserted with two fasteners 23, e.g. screws, such that the supports are fixedly coupled with the frame 10 and the transverse bars 21 steadily stand on the ground. Additionally, the transverse bar 21 has a top side provided with two U-shaped hinged portions 211.

[0020] Each of the armrests 30, which are inverted U-shaped, includes two long rods 31 having bottoms respectively pivoted to the two hinged portions 211 and two elastic pieces (not shown) interconnected with the rods 31 and the hinged portions 211. The two long rods 31 are coupled with an inverted U-shaped handlebar 32 at free ends thereof and the handlebar 32 is installed with a soft pad thereon and is adjustable to move up and down for a user holding the armrests 30 in different height. The armrest 30 lies against a retaining portion of the hinged portion 211 so as to be pivoted toward one direction between a first position, in which the armrest 30 is positioned upright, and a second position, in which the armrest 30 is positioned slantingly. Additionally, the elastic pieces (not shown) can bring the armrest 30 back to the first position.

[0021] The elastic member 40 having high elastic coefficient includes a body 41 having two fixing ends 42 and is disposed below the slots 111. The fixing ends 42 are locked by screws on a bottom side of the top plate 11 and are located at two sides of the slot 111 such that the body 41 of the elastic members 40 stands across the slot 111.

[0022] Each of the sliding seats 50 is composed of a sliding member 51, a guiding post 52 having two screwed ends, and a footpad 53.

[0023] The sliding member 51, which is inverted U-shaped, includes a main plate 511 and two side plates 512 respectively vertically connected with two opposite sides of the main plate 511 and is mounted over the frame 10. The main plate 511 includes a through hole 513 for a top end of the guiding post 52 running through. The guiding post 52 has a bottom end running through a nut 54 and the slot 111 and locked with another nut 55. Two rollers 56 are respectively rotatably installed at the inner sides of the side plates 512 of sliding seats 50 and are respectively inserted in the rails 121. Accordingly, the sliding seats 50 are moved back and forth along the longitudinal axle of the frame 10. Additionally, when the guiding post 52 is moved along with the sliding seats 50, the body 41 of the elastic member 40 is pulled by the guiding post 52 to be extended and transformed.

[0024] Furthermore, one of the side plates 512 of the sliding seats 50 includes a positioning hole 514 in corresponding position to one of the locating holes 122 of the frame 10 and a pin 57 with a pull ring 571 at a distal end thereof is inserted into the positioning hole 514 and one of the locating holes 122 such that the sliding seat 50 is fixed to a predetermined position of the frame 10.

[0025] Each of the footpads 53 is recessed with a threaded hole (not shown) on a bottom side thereof. The guiding post 52 is screwed with the threaded hole at the top end thereof and then the bottom side of the footpads 53 contacts against the top side of the main plate 511 such that the footpads 53 for the user's stepping are fixedly mounted on the sliding piece 51.

[0026] As shown in FIG. 6, the present invention at work is described hereunder. The user respectively holds the armrests 30 with two hands for steady support and steps on the footpads 53 with two feet. When the user exercises leg tendon with the two feet extending outwardly, as shown in FIG. 7, the sliding seats 50 are resiliently retained by the elastic members 40 such that the leg tendon is stretched slowly to prevent against hurt resulted from the leg tendon is stretched too quickly.

[0027] Referring to FIG. 8, one of the sliding seats 50 is fastened to the frame 10 somewhere by the pin 57, namely, one foot of the user is held, and the user stands or sits to move the other foot outwardly. Meanwhile, one of the armrests is swung toward the user to support the user for better balance.

[0028] Referring to FIG. 9, the body exercising trainer 100 further comprises two handgrips 58, which are respectively mounted on the side plates 512 of the sliding member 51. Therefore, the user can kneel beside two sides of the frame 10 and holds two handgrips 58, and then the user moves back and forth along with the sliding seats 50 so as to exercise the user's abdomen.
